Parrots know shapes

Postby Pajarita » Fri Jul 22, 2016 10:43 am

This is an article about a study conducted on Griffin, a CAG with Dr. P (and, if you look closely, you will see that he is also plucking, same as poor Alex) about how parrots can recognize shapes even when they are 'hidden' in the picture. It doesn't surprise me as I remember reading that birds have a completely different 'path' for the images perceived by their eyes to reach the part of the brain that makes sense of them (which is what allows them to 'identify' what they see). They not only have a real smart brain super packed with neurons but also a visual 'shortcut' to it! Cool, isn't it?! And I always thought that it must have something to do with the fact that they fly - I mean, if they couldn't figure out what they are seeing real fast as well as accurately, they would end up flying over potential sources of food without realizing it, not?

Since they nest in holes in trees this ability would probably also help them to spot potential nesting holes, which are unlikely to be seen in any other manner than from the air. They would probably be much harder to spot than would, say, a fruit ready to eat.

I have found that Rambo can identify food by the package it comes in. While putting groceries away he spotted a box of crackers.
I was eating red cherry candy when Rambo decided to see what I had. He looked at it but it did not look like a jelly bean so he ignored it.
